Casio fx-9750G Differential/Quadratic Differential, Inte Instrukcja Użytkownika Pobierz pdf (Strona 16)

• You can use only one variable in the function for input sequence {

ak}.

• Input integers only for the initial term of sequence {

ak} and last term of sequence

{ak}.

• Input of n and the closing parentheses can be omitted. If you omit n, the calcula-

tor automatically uses n = 1.

k Σ Calculation Applications

uArithmetic operations using Σ calculation expressions

Expressions:

Possible operations: Sn + Tn, Sn – Tn, etc.

uArithmetic and function operations using Σ calculation results

2 × S

n, log (Sn), etc.

uFunction operations using Σ calculation terms (

ak, k)

Σ (sink, k, 1, 5), etc.

• Note that you cannot use a Solve, differential, quadratic differential, integration,

maximum/minimum value or Σ calculation expression inside of a Σ calculation

term.

k Σ Calculation Precautions

• Make sure that the value used as the final term

is greater than the value used

as the initial term

. Otherwise, an Ma ERROR will occur.

• To interrupt an ongoing Σ calculation (indicated when the cursor is not on the dis-

play), press the A key.

Sn =

ak, Tn =

k = 1 k = 1
